The invention discloses a high-bearing-capacity lifting device. The high-bearing-capacity lifting device comprises a base, a mounting platform is arranged above the base, a fork-shaped support is arranged between the mounting platform and the base and comprises a first lifting rod and a second lifting rod which are located on the two sides of the base, the top of the first lifting rod is in pivot joint with the mounting platform, and a first sliding shaft is arranged at the bottom of the first lifting rod; a first sliding shaft is arranged at the top of the first lifting rod, a first self-lubricating square shaft sleeve sleeves the outer side of the first sliding shaft, a first horizontal sliding groove is formed in the base, the bottom of the second lifting rod is pivoted with the base, a second sliding shaft is arranged at the top of the second lifting rod, a second self-lubricating square shaft sleeve sleeves the outer side of the second sliding shaft, and a second horizontal sliding groove is formed in the mounting platform; the base is provided with a driving mechanism for driving the first lifting rod and the second lifting rod to do shear type motion. The problem that when a functional iron frame installed on an existing fork type lifting device swings, noise is generated, and therefore the product quality is affected is solved.
